Recently it has been shown that measurement of charge asymmetry of top pair production at LHC excludes any
avor violating Z0 vector gauge boson that could explain Tevatron forward-backward asymme-try (FBA). We consider the general form of a Z0 gauge boson including left-handed, right-handed vector and tensor couplings to examine FBA
and charge asymmetry. To evaluate top pair asymmetries at Teva-tron and LHC, we consider B0 q mixing constraints on
avor changing Z0 couplings and show that this model still explain forward-backward asymmetry at Tevatron and charge asymmetry can not exclude it in part of parameters space
